Aeenaeia lateeifloea, L.—Twin Lakes, Colorado. (347.) Sagina Linn^i, Presl.—Colorado. (341, 342.) Deymaeia* effusa.

The whole plant is hardly three inches high. (619.) Sanoita. Valley, Arizona, at 6,500 feet altitude. Found, so far as I have seen, only among the oak trees and on a gravelly soil. PORTULACACE^. PoETULACA OLEEACEA, L. ? ?—The Specimens from Colorado (989) are all too old to determine with certainty. PoETULACA LANCEOLATA, Engelm.?—Arizona. Poor specimens. Chi¬ ricahua, Southern Arizona, growing on dry sandstone rocks. (521.)
